5x-2y+3z-2x-y+4z solve

I'm not exactly sure how to approach this problem because it does not have an output, but we can combine like terms.

Add all the x, y, and z together with the numbers.

3x-3y+7z is the final answer.

3x - 3y + 7 z, would be the answer because you have to group like terms so first off you would take 5x-2x which will give you 3x then you take - 2y-y which gives you - 3y so that you would have 3x-3y and then you would take 3z+4z which would give you 7z therefore the solution to the system is 3x-3y+7z
